Removed outdated text about libc_r replacing libc (it now provides

just libc functions wrappers), and updated text to match reality:
there are three threading libraries in FreeBSD these days.

Removed instructions of how not to build libc_r, it's documented in
the make.conf(5) manpage already.

Removed description of the FreeBSD-specific gcc(1) option, -pthread.
While it's still provided (for backwards compatibility reasons),
its usefulness is questionable.
